Ports! Can't live with 'em can't live without 'em. But which ones, eh?

I have been guilty, on occasion, of following advice from EE without paying too much attention. Particularly when it comes to ports. Can we establish some rule-of-thumb typical standards for SBS-2003? Which ports should ALWAYS be closed? Which ports should typically be open for a SBS-2003 server used as such:

A 2x NIC DC with exchange no VPN no FTP no remote web/email
B 2x NIC DC with exchange with remote web/email no VPN no FTP
C 2x NIC DC with exchange with remote web/email with VPN no FTP
D is FTP ever a good idea on a SBS?
E should port 80 ever be open?

I realize there maybe no definitive

I was hoping this would develop into a good discussion on ports.

i.e. different ports may be open one one NIC, and closed on the other.

Every port should be open on the routers. Or maybe not.

I understand if there is less enthusiasm there than there is here.
